Part 03: How to force quotas limit to Kubernetes Storage

This blog is a continuation of previous blog series https://goglides.io/2020/03/03/limit-range-kubernetes/

Limiting Storage resources

Using LimitRange it is possible to enforce minimum and maximum size of storage resources that can be requested by each PersistentVolumeClaim in a namespace.

Create a file limitrange-storage.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: limitrange-storage-demo3
---
apiVersion: v1
kind: LimitRange
metadata:
  name: storagelimits
  namespace: limitrange-storage-demo3
spec:
  limits:
  - type: PersistentVolumeClaim
    max:
      storage: 2Gi
    min:
      storage: 1Gi

Apply the YAML file using:

kubectl apply -f limitrange-storage.yaml

Describe the created object:

kubectl describe -f limitrange-storage.yaml

Output:
Name:         limitrange-storage-demo3
Labels:       <none>
Annotations:  kubectl.kubernetes.io/last-applied-configuration:
                {"apiVersion":"v1","kind":"Namespace","metadata":{"annotations":{},"name":"limitrange-storage-demo3"}}
Status:       Active
No resource quota.
